See my delayed correction to my own ramblings.
6400 mils to the circle of 32 points means that 200 mils equals one
point and 50 mils equals a quarter point. After that, it is just a
matter of getting the naming of the points and quarter points right --
without dropping some of the words as I managed to do.
0 N
50 N 1/4 E
100 N 1/2 E
150 N 3/4 E
200 N by E
250 NNE 3/4 N
300 NNE 1/2 N
400 NNE
500 NNE 1/2 E
600 NE by N
700 NE 1/2 N
800 NE
The "by" points are named from the cardinal and ordinal points (e.g. N
or NE) not from the ones between (e.g. NNE). The quarter and half points
are named from all of those (e.g. N, NE or NNE) but not from the "by"
points -- or so they have been on the few compasses I have examined
which have shown quarter points.
And that replaces another blunder on my part, in which I wrote:
>>The

>>ordinal point (e.g. North or North East), not from the intermediate

That confused the rule for naming "by" points with the rule for naming
quarter and half points. (I was obviously not having a good day yesterday!)

"North by North West" isn't a compass point. The "by" points are only
named as "by" one of the cardinal points (North, South, East or West).
Think of the "by" meaning "a point in the direction of" -- N by E is
almost North but a point towards the right. There is no need to specify
whether it is towards the NNE, NE or E. All are in the same direction
and economy of wording (plus concentration on the bigger thing) means
that just "East" is used.
I make NW to be 5600 mil (6400-800, where the 800 is 200 per point and
there are four points to 45 degrees), so 5800 mil would be NW by N.
[Maybe that was what Hitchcock wrote. I'm not familiar with that
reference to his work.]

Having (inadvertently) demonstrated that the points system was beyond my
abilities, when I had attempted to show the reverse, I was trying to add
a bit of levity. The "lunars" are the lunar observations that get so
much time on this list (as they should), not a different unit of time.
I guess there is a moon-based time unit in the lunar month. It is still
the basis of the Islamic calendar, which is still very much in regular
use in much of the world. [When I was based in Bangladesh, the
English-language newspapers had three dates on the masthead: Western,
Islamic and Bengali. Following the Mongol conquest of India, the new
Islamic rulers discovered that their lunar calendar didn't work very
well in an area where rice planting had to be timed to the solar year
and its monsoon cycle. Hence the invention of a similar but different
Bengali calendar. Now the country seems to run on three different
calendars for religious, secular and business/international purposes
respectively.]
